Raspberry Pi Gpio Pins

24x gpio pins.

Raspberry pi gpio pins. 1x serial uarts rpi3 only includes mini uart 2x spi bus. 2x 5v power pins. The equipment that i use in this raspberry pi gpio tutorial is listed below. 1x i2c bus.

A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. The raspberry pi has two i2c connections at gpio 2 and 3 sda and scl are for i2c0 master and physical pins 27 and 28 are i2c pins that enable the pi to talk to compatible hat hardware. Micro sd card if you re using a raspberry pi 2 3 or 4 8 gb recommended ethernet cord or wifi dongle only if you re controlling. Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes.

2x 3 3v. Raspberry pi 40 pin gpio header. Hardware interfaces for the raspberry pi 2 and raspberry pi 3 are exposed through the 40 pin header j8 on the board. For a great guide to getting started using the gpio pins in a simple project try out our getting started with raspberry pi gpio project getting started with gpio on a raspberry pi if you though the arduino was cool just wait till you get your hands on a raspberry pi these things are amazing.

It s the 40 pins you can see on the raspberry pi near the edge. 5 minutes to read. The older iterations of the rpi such as the raspberry pi model b will only contain a total of 26pins. The models that use this configuration are.

Do not provide the pins with greater than 3 3v. The comprehensive gpio pinout guide for the raspberry pi. Knowing the power limitations of the gpio pins and also understanding what you re plugging in is a must. If you are reading the raspberry pi copyright statement printed on the pcb then pin 1 is in the bottom left and pin 40 is in the top right.

Raspberry pi 40 pin gpio layout. It also includes dozens of pinouts for raspberry pi add on boards hats and phats. This is a quick way to fry your pi. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header.

This gpio pinout is designed to be both a quick and interactive reference to the raspberry pi gpio pins plus a comprehensive guide to your raspberry pi s gpio interfaces. The majority of raspberry pi models use the same 40 pin header. If you re using the raspberry pi b 2 zero 3 or the latest raspberry pi 4 model b you ll discover that your board have a total of 40 gpio pins. Not only does the single board computer support more ram a faster processor speed and expanded peripherals but the gpio pins retain their standard functions set by previous models along with extra functions for existing pins.
